Technical punto 1.2 suck noise

[punto steve]

when accelerating there's a suck or blowing sort of noise from engine around the alternator not as loud or easy to determine when stoped and just reving the engine any idea's any one

 

[Anfield]

its most proberly your throttle body.
(dont know what its called) but the round circle part inside your throttle body makes a hissing/sucking noise when its near fully open, it just makes that noise. if you have got a induction kit on your engine it will enhance the sound.
